#X text 338 334 'q' controls the filter resonance. The resonance input
is for 'extra' resonance.. :);
#X text 400 171 <- keep q below 0.1;
#X text 339 370 The filters don't use the same scale for frequency.
Bandpass frequency seems to be in Hz. If the frequency is set too high
\, LOUD aliasing is produced.;
#X text 339 418 The bandpass filter is very sensitive to q - normal
range is 0 to 0.1.;
